As a result of your post, I went and looked up the specs of the 26' uhaul.Nope, 25,999 gvw, 7,500 max allowable tow, plus a huge overhang in the rear. I would bet the first turn will jackknife it.
25,999 is GVWR, meaning the max it can weigh fully loaded. Empty it weighs about half that. As you pointed out, the tow rating is less than 1/3 of what would be needed to tow an M52A2.
Even given a hypothetical tow vehicle with a tow rating of 25k the brakes on the M52A2 would need to be operational. To tow an M52A2 without its brakes helping needs a tow vehicle weighing 35k or so. Think HEMTT.
A 26' uhaul is not up to the task. It will get pushed all over the road by the truck in tow, and this presumes the hitch doesn't simply shear off by overloading it by a factor of three, and at an angle. (I don't really think the hitch will break. The tow vehicle doesn't have the traction necessary to break it. The tow vehicle will slide before the hitch breaks. The tow vehicle *will* slide, early and easily.)
Stopping distance is going to be loooooooong. And attempted stops in anything other than a straight line will push the tow vehicle sideways. This presumes dry road. Wet or icy will make it a thousand times worse.
This combination results in adequate traction for braking for about 13k, and a combined weight of around 35k.
I've ignored legalities, deliberately. It isn't legal, but that's almost irrelevant to this discussion.
A 1ton pickup truck and a heavy gooseneck trailer is a far better option than flat towing with the proposed combination. On the gooseneck, even if you go well over GCVWR, you at least have brakes and proportional traction.
Consider also that the uhaul towing the MV is going to look funny to every LEO and DOT who sees it. They're going to want to pull it over for a closer look. Once they get a close look they're going to start writing bunches of tickets.
Again, the chances of some kind of badness happening are high and the magnitude of the potential badness is off the scale.
OP, if you do it and get away with it without something bad happening please post the results....
